Cogeneration is crucial, says IEA

The supply of heat is largely ignored in the energy and climate change debate, even though it represents nearly half of the world’s final energy consumption, says the ‘Co-generation and Renewables: Solutions for a low-carbon energy future’ report from the International Energy Agency (IEA).

The report observes that cogeneration is attractive to both policy-makers and private users and investors because it delivers a range of energy, environmental and economic benefits.

These benefits include: dramatically increased energy efficiency; reduced CO2 emissions; increased energy security through reduced dependence on imported fuel; cost savings for the energy consumer; and beneficial use of local energy resources - particularly through the use of waste, biomass and geothermal resources in district heating and cooling systems - providing a transition to a low-carbon future.

According to the latest figures, heat represents 47% of energy consumption, compared with 17% for electricity, 27% transport; and 9% for non-energy use, which covers fuels that are used as raw materials in different sectors, such as oil used to make plastics.

Oil, coal and gas account for more than two-thirds of the fuels used in meeting this significant demand for heat, which causes significant levels of CO2 emissions into the earth’s atmosphere.
